The prices of consumer goods do not always exactly follow the CPI. The following chart shows several consumer items, along with

UNO [17]

Customer price index is the price index which measures the weight average of price of basket of customers goods or services. The reasonable estimate of the current customer price index is 195. The option B is the correct option.

Given information-

The data table for the given problem is attached below.

<h3>Customer price index</h3>

Customer price index is the price index which measures the weight average of price of basket of customers goods or services. It can be given as,

$CPI_t=\dfrac{C_t}{C_0} \times 100$

Here $C_t$ is the cost of market basket in current period and $C_0$ is the cost of market basket in the base period.

Cost of market basket in current period is.

$C_t=126.85+29.95+2.25+44.25\\C_t=203.3$

Cost of market basket in 1983 is,

$C_0=67.45+15.25+1.15+22.85\\C_0=106.7$

Put the value in the customer price index formula,

$CPI_t=\dfrac{203.3}{106.7} \times 100\\CPI_t=190.5$

Thus the value of current CPI is 190.5 which is near about the 195.

Hence the reasonable estimate of the current customer price index is 195. The option B is the correct option.

Can you please help me with this I been stuck for a long time

yarga [219]

Answer:

Step-by-step explanation:

2.671 = (2.67 × 100)(1 × 100) = 267100. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 267100 is also equal to 267100 when expressed as a mixed number.

Selena was comparing the flying speeds of different birds in science class. Which of the three birds flies fastest? Why?

Mashcka [7]

Answer:

Option C. The robin flies fastest because its rate is 15 m/s

Step-by-step explanation:

Let

x -----> the time in seconds

y ----> the distance in meters

The speed is equal to divide the distance by the time

In this problem, the slope or unit rate of the linear equation is the same that the speed

<em>Robin's Flight</em>

<em>Find the slope</em>

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take two points from the table

(2,30) and (3,45)

substitute in the formula

$m=\frac{45-30}{3-2}$

$m=\frac{15}{1}$

$m=15\frac{m}{sec}$

<em>Cardinal's Flight</em>

$y=10x$

$m=10\frac{m}{sec}$

<em>Blue Jay's Flight</em>

take two points from the graph

(0,0) and (2,20)

substitute in the formula

$m=\frac{20-0}{2-0}$

$m=\frac{20}{2}$

$m=10\frac{m}{sec}$

Compare

The robin flies fastest because its rate is 15 m/s
